Title: Digital servo controller
Inventor: ROOUERU JIEEMUSU SUCHIYUWAATO
IPC: G05B19/23
Filed: 1989-09-19
Abstract: PURPOSE: To eliminate speed quantization errors by operating a speed field back loop by using a variable sample rate speed estimated value under a low speed state. CONSTITUTION: Speed data are sent to a speed compensation loop 65 and the operation of the loop 65 is decided by whether a motor is driven at a high speed or driven at a low speed. Under a high speed state, the speed data fed back to a mixer 50 are the ones for which a system speed constant K2 is multiplied with the encoder output of an encoder 55 with the motor as before. Under the low speed state, the loop 65 is operated by a variable sample rate decided by the encoder output. Thus, under the low speed state, the speed quantization errors are reduced, noise is reduced and the operation is ensured.

Title: Level detector with level alarm
Inventor: KUNO NOBORU
IPC: G01F23/00
Filed: 1984-11-19
Abstract: PURPOSE:To prevent frequent generation of alarms due to the waving of the liquid level, by providing liquid level sensors respectively for detecting the filling and decreasing levels with level sensors for detecting the upper and lower levels respectively. CONSTITUTION:As the water level 5 passes by a lower limit detection sensor 9, a contact f-1 is turned ON while as it does by a filling level detection sensor 3, a contact (f) turns ON. Then, a relay RL1-1 starts and contacts rl1-2 and rl1-1 are also turned ON to generate an alarm from a monitoring section 7. Then, the water level 5 lowers below the filling level detection sensor 3 and the contact (f) is turned OFF while the relay RL1-1 will not be turned OFF. On the other hand, when the water surface falls below the lower level detection sensor 9, the contact f-1 is turned OFF and the relay RL1-1 and the contacts rl1-2 and rl1-2 are both turned OFF to halt the generation of the alarm. This eliminates intermittent alarming due to the waving of the water level 5 to prevent frequent interrupt into a computer at the monitoring section.
